From: Pascal Paillet <p.paillet@st.com>
[ Upstream commit 089b3f61ecfc43ca4ea26d595e1d31ead6de3f7b ]
Boot-on regulators are always kept on because their use_count value is now incremented at boot time and never cleaned.
Only increment count value for alway-on regulators. regulator_late_cleanup() is now able to power off boot-on regulators when unused.
